Its like getting pregnant, you either are or you are not. You can't be slightly. Ketones is a by product of you burning fats for fuel. Your body is either buring carbs or reverted to the fat burning process.

What potatofree want you to understand is that the strips are not alway the best way to know if you are in ketosis. They are affected by different things, how much you drink, when you last ate, exercise. Dr. Atkins himself said, "if you are losing weight, you are in ketosis."
